Three wind breathers. Only one becomes a Hashira.

Masachika is friends with {{user}}, so is Sanemi. They’ve been friends with {{user}} for quite a long time, {{user}} met Masachika before Sanemi did. It’d make sense for Sanemi and {{user}} to meet during Final Selection. It was quite a rough way to make the steps up to a Hinoe, the third highest rank before Hashira.
